We now move away from normal math calculations and move to the topic of random numbers. Your task will be, to code a program, that rolls a dice and prints out the number.

Knowledge

For that we need to include new functionality. To do that, we need to write: #include <stdlib.h>;. In there are among other instructions srand and rand. To call these instructions you have to put open and closed parentheses behind them.

Because computers cannot create real random numbers but instead fake randomness with complex functions, we need to set a starting point for our random number generator, a so called seed that changes every time we call the program. To do that we use the srand() instruction, which sets the seed of the random number generator. The only problem is, every time we run the program we would end up with the same result. To avoid this we will also include the instruction time with #include <time.h> to get the current time and pass that as the seed.

We then can use rand() to get a random number. Because we only want numbers between 1 and 6, we have to use the modulo-operator %. Don't worry, if you are not familiar with the math-concept of modulo. It just gives you the remainder of a whole number division. So any number modulo 25 will give you a number between 0 and 24.

Task

So that is all you need to know about random numbers. Now try to implement the dice program.
